A pinch of silver and copper: metal combinations give biomedical silicone strong nano-properties

Silicone elastomers are widely used for biomedical applications and products. One major challenge for biomedical applications is to control the ingrowth of silicone-based implants and to avoid bacterial infections on device surfaces. The use of ions from metals like silver and copper is a promising, long-lasting method to achieve such bioactive effects. Researchers have now found a novel effect caused by a combination of copper and silver nanoparticles in silicone. By fabricating bioactive nanocomposite materials that release these ions in specific concentration levels and during a long time, manufacturers can control the bioactive effects of their medical devices or implants.

Siltronic AG Joins imec’s GaN-on-Si Research Program to Develop Technology for Next-Gen Power Semiconductors and LEDs

Siltronic AG and the Belgian nano-electronics research institute imec have concluded an agreement to collaborate on the development of silicon wafers with a gallium nitride layer as partner of imec's GaN-on-Si industrial affiliation program (IIAP). The endeavor aims to enable production of solid-state lighting (e.g. LEDs) and power semiconductors of the next generation on 200 mm silicon wafers.

Patent analysis and product survey on use of nanomaterials in lithium-ion batteries

The efforts undertaken in developing renewable energy sources to reduce our dependence on fossil fuels include major research and investment in advanced electricity storage technologies. Among the various existing technologies, lithium batteries are considered as the most competitive power source because of their high energy density, superior power capability, design flexibility and longer lifespan. This article provides an overview of the current patent landscape of rechargeable Li-ion battery, with a focus on the recent developments on nanomaterials and nanotechnologies used for anode, cathode, and electrolyte materials, and the impact of nanomaterials on the performance of rechargeable lithium batteries. Effort has also been taken to identify key players, emerging trends and applications in this area.

New technique advances bioprinting of cells

By extending his pioneering acoustical work that applied sound waves to generate droplets from fluids, Dr. Utkan Demirci and his team at Harvard Medical School's (Brigham and Women's Hospital) Bio-Acoustic Mems in Medicine Laboratory report encouraging preliminary results at an early and crucial point in a stem cell's career known as embroid body formation.

Shedding light on Kondo correlations

Scientists from ETH Zurich, LMU Munich, Princeton and Yale Universities have used resonant laser absorption to examine how a quantum dot with Kondo correlations responds to a quantum quench, i.e. to an abrupt change in the interactions that give rise to Kondo correlations in the first place.

Nanowires offer opportunities for improved LEDs

Researchers from the FOM Institute AMOLF, together with colleagues from Philips Research, Eindhoven University of Technology and Delft University of Technology, have made special nanostructures that could be used as light-emitting diodes (LEDs). These nanostructures can be used to control the direction of the emission.
